A DEX on Moonriver, Moonbeam and Kava, with farms, a launchpad and NFT reward staking

Chains: 3; Moonriver (Oct 2021), Moonbeam (Jan 2022), Kava (Apr 2023)

The challenge

AlphaDEX needed an exchange, farms and a launchpad on Moonriver, then the same on Moonbeam and Kava.

Token sales needed tiered allocations, whitelists and timed claims that buyers could trust.

Our approach

One codebase, three chains

We started from the SushiSwap interface and SDK, added AlphaDEX's chain addresses and deployed on Moonriver, Moonbeam and Kava.

A launchpad with tiers

IDO contracts use a clone factory, tiered allocation levels, Merkle whitelists and Chainlink price feeds.

Staking that rewards in NFTs

ROAR and LP staking, with lock periods and tiers, rewards stakers with NFTs.

What we built

The exchange interface, SDK and farms on Moonriver, Moonbeam and Kava.
IDO launchpad contracts, launchpad pages and an admin panel.
NFT reward staking for ROAR and LP tokens.
A vesting claim portal and a bulk token sender.
An analytics dashboard and subgraphs.

How AlphaDEX was built

Services behind this work

Security and quality

IDO whitelists were checked by Merkle proof, and a sale could be cancelled before it closed.
Pairs and farms were indexed in subgraphs, so the analytics pages read on-chain data.
